RIVETING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 468,734, dated February9, 1892. Application filed December 31, 1888 Serial No. 295,027. (Nomodel.)

To all whom it may concern.-

Be it known that I, JACOB J. UNBEHEND, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Receivers for Riveting-Machines, of which the following,taken in connection with the accompanying drawings, is afull, clear, andexact description.

My invention relates to an improvement in a receiver or pocket forrivet-inserting machines, and is especially designed for use inrivet-machines of the kind described in my application (Case A) of evendate herewith, and has for its object the production of a simple andeffective device through which the plunger is operated and to whicharivet is conducted by a suitable conveyor and then held there by in thedesired position, shank downward, in the path of the plunger or otherinserting mechanism.

To thisjend it consists, essentially, in a receiver or pocket throughwhich the plunger is operated and which is provided with yieldingshoulders or rivet-holders adjacent to the discharge of the conveyoryieldingly holding the rivet and adapted to be forced outward ordisengaged therefrom when the inserting mechanism forces the rivetdownward through the receiver into the desired position.

It furthermore consists in the detail construction and arrangement ofthe parts, all as hereinafter more fully described, and pointed out inthe claims.- V

In specifying my invention reference is had to the accompanyingdrawings, forming a part of this specification, in which like lettersindicate corresponding parts in all the views.

Figure 1 is an elevation of my improved rivet receiver or pocket inoperative position upon a supporting-bracket, a detached portion of theconveyer and plunger being also shown. Fig. 2 is an elevationof thedetached receiver or pocket, further illustrating the construction andarrangement of the yielding rivet-holders. Fig. 3 is a longitudinalvertical section of the receiver or pocket, taken on line as as, Fig. 1,the yielding holders for the rivet being sprung out to allow therivet-head to pass thereby when actuated by the insert-' ing mechanismclearly illustrating the construction and arrangement of the parts. Fig.

4 is a like longitudinal section to that illus trated in Fig. 3, therivet being shown as being disengaged or discharged from the guideway inthe receiver. Fig. 5 is a longitudinal vertical section taken throughthe receiver on line 3/ y, Fig. 2, illustrating the detail constructionof the'parts; and Fig. 6 is ahorizontal cross-section taken on line/e,2, Fig. 1, illustrating a rivet in said receiver.

A represents my improved receiver or pocket, through the chamber orguideway a of which a plunger B or other suitable actuatin g mechanismis operated,forcingthe rivet through said receiver or pocket into anydesirable article placed beneath the discharge a of the same andinterposed between said discharge a and any suitable die or stop, (notshown,) but which may be of the kindillustrated in my aforesaidapplication (Case A.) The receiver or pocketA is supported in anydesirable position upon asuitable bracket D, and, as preferablyconstructed, has a :movement upon said bracket in the same line as thatof the rivet when beinginserted into the desired article.

When inserting rivets into any article, it is very desirable that therivet shall be fed di-. rectly to the same in the desired position, andit will be seen that this movement of the re ceiver or feeding-tubeallows articles of various thickness to be interposed between thedischarge a of said receiver and the stop or die for the rivet, since,1fthe article is thin, the receiver is actuated to contact with the same,or if it is thick the movement of the receiver is stopped by contact ofthe rivet with the article to be provided with the rivet.

To allow of this movement of the receiver A,

I provide thereon the extension A, mounted upon the rod E, secured inlugs D of the re ceiver-supporting bracket D. As presently described,when the plunger is inserting the rivet the receiverA moves downward onthis rod E until the lower face A of the exten- 5 sion A abuts againstthe top face of the lower projection D, or until the rivet abuts againstthe article to be provided with the rivet. After the operation of therivet-inserting mechanism the receiver is withdrawn from this pozoosition by means of a suitable spring F or otherdesirable means securedthereto,

The conveyer G is mounted in any suitable manner, preferably in abearing-face D of thebracket D, and is provided with its discharge G,mounted in a slot A of the receiver,

which is provided with a cut-out a, through which the rivet is insertedinto the chamber or guideway a of the receiver. Directly on a line orbeneath the discharge of the conveyer G, I provide shoulders or holdersII, which project within the receiver or feedingtnbe through slots Aprovided therein, and which shoulders are adapted to engage the rivet,preferably by the head, when the same is fed into the receiver by theconveyer G. Then the plunger or inserting mechanism is forced downwardupon the rivet, which is held by these holders or plates in the desiredposition, shank downward, it will be seen that to insure operation ofthe machine the said shoulders must be yielding or must be removablefrom the rivet-h ead. To attain this result I secure the outer ends ofthese shoulders or holders to springs 1, preferably fastened to theoutside of the receiver by screws 2' or other desirable means. When theplunger engages the head of the rivet, forcing the same downward, theseshoulders H will be readily forced from under the head against theaction of the springs I, which retain these shoulders H in this theirnormal position. To allow of the ready springing apart of the shoulders,I preferably form the same with a bevel h upon the top face thereof,which bevel also serves to center the rivet. As shown in Figs. 3 and 4,these shoulders H, projecting within the guideway a are of sufficientsize to allow the head of the rivet to be easily forced therethrough,and at the discharge of the receiver I provide the shoulders or jaws aVhen the rivet has been forced downward and has beendisengaged from theholders H, the same continues in its downward movement until its headabuts with the shoulder a in the discharge of the receiver, at whichpoint its downward movement is stopped, and

the receiver is immediately forced downward,

suitably approximating the discharge a to the article to be providedwith the rivet. The discharge a of the receiver is adapted to closelypress the rivet-shank when the same is being forced therethrough for thepurpose of positively guiding the same into the article to be riveted.

Extending upwardly from the dischargeopening a of the receiver is a slitor slot a dividing the same into two halves and allowing them to besprung apart when the rivet is forced through the discharge. Therivetshank is-of sufficient size to slightly spring ceiver is formed ofspring metal, and when the rivet has been inserted and the plungerwithdrawn readily springs back to the desired position, and theretaining-shoulders H, by reason of the springs I, also spring back totheir normal position upon the withdrawal to its normal position of theplunger.

The operation of my machine is as follows:

springs the retaining holders back out of engagement with the rivet,forces the same down the guideway of the receiver, and then engages thehead thereof with the shoulder or jaws a in said receiver, forcesdownward the receiver to the desired position, and then springs apartthe halves of said receiver, allowing the rivet to be forcedtherethrough.

It will be understood that where articles of the same thickness are tobe provided with rivets it is usually unnecessary to allow of a movementto the receiver, and it will be also seen that in some cases theshoulders a may be dispensed with and the rivet forced directly throughthe guideway without springing apart the receiver and that other changesmaybe made in the detail construction and arrangement of the receiverwithout departing from the spirit of my invention, which is theproduction of yielding shoulders which shall retain the rivet in' thedesired position, shank downward, until the operation of theplunger,preventing all tipping of the rivet when being discharged into thereceiver and insurin g a positive operation of the same.

My improvedrivet-receiver may also be used as described in myapplication (Case A) of even date herewith, Serial No. 295,026, for thepurpose of feeding rivets one by one to a saw or other device forbifurcating the same in order to prepare them for ready entrance intoarticles, allowing the bifurcated shank to be clinched, thus securelyretaining the rivet in position.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In the receiver of a rivet-setting machine having separable jaws, thecombination of a chamber having slots in the walls thereof and yieldingplates attached at their outer ends to suitable supports, their innerends projecting through the slots and being adapted to support a rivet,substantially as described.

2. In the receiver of a rivet-setting machine, the combination of achamber, the slots in the walls thereof, yielding plates projectingthrough said slots and adapted to support a rivet, and movable arms towhich said plates are attached, substantially as specified.

3. In the receiver of a rivet-setting ma chine, the combination of areciprocating chamber or guideway a for guiding the rivets and adjustingthe same to the desired po- IIO sition, a guide for said chamber, andreciprocating mechanism for reciprocating said chamber, with slots A inthe Walls of said chamber a and yielding plates or shoulders H, attachedat their outer ends to suitable supports, their inner ends projectingthrough the slots A and adapted to support a rivet, substantially as andfor the purpose set forth.

4. In the receiver or feeding-pocket of a rivet-setting machine, thecombination of a reciprocating split chamber 0 reciprocating mechanismfor reciprocating said chamber a shoulders a provided upon the oppositedivisions of said chamber, and slots A in the Walls thereof,withyielding shoulders or plates II attached at their'outer ends to suitablesupports, their inner ends projecting through said slots and beingadapted to support a rivet, substantially as and for the purposespecified.

5. In the receiver or feeding-pocket of a rivet-setting machine, thecombination of yielding holders or shoulders H, the springs I,

connected to said holders, and the jaws or shoulders a connected to thespring 05 the said holders and jaws being secured to the arm A and soarranged in relation to each other that the opening between the jaws orshoulders a registers with the like space of the holders H,substantially as and for the purpose specified.

In testimony whereof I have hereunto signed my name, in the presence oftwo attesting witnesses, at Syracuse, in the county of Onondaga, in theState of New York, this 26th day of December, 1888.
